You've probably spent hundreds of hours running across the grassy plains of Mondstadt or scaling the jagged cliffs of Liyue, but have you ever actually looked up? I mean, really looked. If you stop and stare at the moon or the stars in Teyvat, something feels... off. It’s not just the pretty colors. There is a persistent, nagging theory supported by massive chunks of in-game dialogue that suggests the other side of the sky Genshin players see is actually a massive, artificial lie.
Scaramouche—back when he was still a Harbinger and not our favorite moody wanderer—dropped the biggest bombshell in the game's early history during the Unreconciled Stars event. He looked the Traveler in the eye and said, "The stars, the sky... It's all a gigantic hoax. A lie."
Since then, the community has been obsessed. We aren't just talking about a skybox in a video game. We are talking about a fundamental lore pillar that suggests Teyvat is encased in a "false sky." This isn't just flavor text; it changes everything we know about the Sustainer of Heavenly Principles and the very nature of the world we’re trying to save.
The Scaramouche Revelation and the False Sky
Most players who joined after Version 1.1 missed the literal foundation of this theory. During the event, Scaramouche explores a fallen meteorite and comes to a conclusion that even Dottore apparently agrees with: the sky is fake. It’s a dome. It’s a ceiling.
Think about the implications for a second. If the sky is a lie, then "Fate" in Teyvat—which is dictated by the constellations—is also a lie. In Teyvat, everyone's life is written in the stars. If those stars are just glowing dots on a ceiling controlled by Celestia, then free will doesn't exist. You're basically living in a high-stakes version of The Truman Show.
Dottore later reaffirms this in the Sumeru Archon Quest. He makes a deal with Nahida, trading top-tier information for her Gnosis. Part of that "truth" involves the fact that the sky is a fake. Nahida, the God of Wisdom herself, was visibly shaken by this. Why would a god be surprised? Because the illusion is so perfect that even the Archons might be kept in the dark about the true nature of the world's boundaries.
Why does Celestia want a ceiling?
It’s about control. Pure and simple. By creating a "Firmament," the powers-at-be (Celestia) can keep the inhabitants of Teyvat contained. It prevents them from seeing what is actually out there in the "Sea of Quanta" or the "Imaginary Tree"—concepts MiHoYo fans know well from Honkai Impact 3rd and Honkai: Star Rail.

The Upside-Down World Theory
If you look at the design of the Spiral Abyss, you’ll notice something weird. You go down to go up. You descend into the depths of the earth, yet the further you go, the more the background looks like... space. This has led to the "Other Side of the Sky" theory which posits that Teyvat is actually inverted.
Imagine a hollow planet. We are living on the inside of the shell, looking toward the center.
- The Abyss: It leads to the "true" outside.
- The Sky: It's the core of the planet, masked by an illusion.
- The Surface: Just a layer sandwiched between two infinities.
This explains why the stars in the Abyss look more "real" or at least more chaotic than the orderly constellations we see from the surface. When the Traveler's sibling says they have "reached the end of their journey," they might mean they’ve actually pierced through the false sky and seen the horrifying reality of what lies beyond.
What is actually on the other side?
Honest answer? It's probably a wasteland. Or worse, it’s the "Honkai." For those who don't play MiHoYo's other games, the Honkai is a force of destruction that wipes out civilizations that get too technologically advanced.
Celestia might actually be "protecting" Teyvat by keeping it in a bubble. By capping the sky, they limit the world's growth and keep it hidden from cosmic predators. It’s a gilded cage. You get to live, but you never get to grow beyond what the "Heavenly Principles" allow.
The Khaenri'ah Connection
Khaenri'ah was a nation without a god. They didn't look to the "stars" for guidance; they looked to human ingenuity. It’s highly likely they discovered the truth about the other side of the sky Genshin lore. They saw the ceiling. They tried to break it. And what happened? Celestia dropped the hammer—literally—and nuked the entire civilization.

If you start asking too many questions about the ceiling, the landlords tend to get angry.
The Moon Sisters and the Solar Chariot
Ancient Teyvat lore mentions three sisters: Aria, Sonnet, and Canon. They were the moons. They were the ones who sat in the "Lunar Palace." During a great calamity (probably the arrival of the Primordial One), they turned on each other. Now, only one corpse remains—the moon we see in the sky.
But here’s the kicker: the moon in Teyvat doesn’t behave like a real moon. It doesn't have phases that align with a 3D orbit. It’s static. It’s a painting. Or a satellite.
The "Solar Chariot" is another piece of the puzzle. Ancient texts describe it falling and breaking. This sounds less like mythology and more like a space station crashing. If the "sky" is a mechanical structure, then the sun and moon are just parts of the machinery.
The Loom of Fate
In the most recent Archon Quests, we hear more about the "Loom of Fate." The Abyss Order wants to "reweave" fate. You can’t reweave something unless it’s made of fabric. If the sky is a tapestry (the false sky), then the Abyss Order is trying to rip the fabric down to see what’s behind it.
Basically, the Traveler is stuck in the middle of a cosmic renovation project.

Breaking the Fourth Wall
There is a meta-theory that the "other side of the sky" is actually us—the players. While that sounds a bit too Matrix for a fantasy RPG, MiHoYo loves fourth-wall breaks. The "stars" could be the data of the game itself. However, within the internal logic of the story, it’s more likely that Teyvat is a "world-seed" or a laboratory experiment being run by the Primordial One (Phanes).
Practical Next Steps for Lore Hunters
If you want to see the evidence for yourself, you don't need a PhD in Teyvat history. You just need to know where to look.
- Read the 'Pale Princess and the Six Pygmies': This in-game book series is notoriously difficult to collect but contains huge hints about the "Land of Night" and the false nature of the world's light.
- Observe the Sky in the Abyss: Next time you're clearing Floor 12, don't just rush the enemies. Look at the horizon. Compare it to the sky in Fontaine or Sumeru. The difference in "depth" is intentional.
- Check the Artifact Descriptions: The Tiara set (Tiara of Torrents, etc.) describes the era when people could hear the voice of the heavens directly, and how that changed when the "sky" became silent.
- Re-watch the 'We Will Be Reunited' Cinematic: Watch the way the sibling looks at the world. It’s not a look of wonder; it’s a look of disdain. They know the sky is a lid.
The mystery of the other side of the sky Genshin isn't going to be solved until we reach Snezhnaya or even Khaenri'ah. But the breadcrumbs are everywhere. Every time you wish and see that shooting star, remember: you aren't pulling a hero from the heavens; you're likely pulling a soul through a gap in a very expensive, very dangerous ceiling.
Keep your eyes on the stars, but don't trust a single one of them. Underneath the beauty of Teyvat lies a mechanical coldness that the Traveler is only just beginning to understand. If the sky falls, it won't be a metaphor—it'll be the shattering of a glass cage.
For now, the best thing you can do is keep leveling your characters and hoarding Primogems. When the sky finally cracks open, you’re going to want to be ready for whatever is looking back through the hole. Don't stop at the Archon Quests; dive into the weapon descriptions and the obscure library books in the Knights of Favonius headquarters. That’s where the real truth is hidden.
